MOUNT FOR TELESCOPING ANTENNAS Filed July 2, 1964 2 Sheets-Sheet 2 United States Patent 3,241,144 MOUNT FOR TELESCOPING ANTENNAS Jerome Berger, North Woodmere, N.Y., assignor to JFD Electronics Corporation, Brooklyn, NY. Filed July 2, 1964, Ser. No. 379,900 6 Claims. (Cl. 343-402) The instant invention relates to telescoping antennas and more particularly to an assembly for mounting tele scoping antennas to receiver units and the like providing the dual functions of mounting the antenna to the housing of the receiver set and maintaining adequate friction upon the antenna ball and socket assembly.

Telescoping antennas find wide-spread use throughout the receiver field and particularly in the field of portable receivers, such as for example portable radios, transceivers and television sets and the like. The design requirements for telescoping antennas in the portable receiver field are such that the antenna assembly must be capable of being telescoped out of sight when the receiver set is not in use. The telescoping antenna assembly, in folding into the receiver housing, must not interfere with or come in contact with either components of the receiver set or any high voltage points which exist within the housing. The telescoping antenna assembly undergoes extension and collapse rather frequently and must have the ability of retaining any position to which it is oriented without collapsing.

Also, due to such continued use, the ball and socket joint about which the telescoping antenna pivots, must be capable of being readily and simply adjusted in order to maintain adequate friction of the ball and socket pivot assembly.

The telescoping antenna mount of the instant invention provides all of the above functions and, in addition, is simple in design so as to minimize raw material cost and further is relatively easy to assemble and disassemble for installation and maintenance purposes, respectively.

The instant invention is comprised of a telescoping antenna comprising a plurality of elongated tube and rod members which are adapted to telescope into one another in the fully collapsed position and further adapted to extend to a length which is respectively equal to the sum of the length of the individual rod and tube elements comprising the telescoping antenna portion.

The outermost elongated tube forming the telescoping antenna extends through an opening provided in a spherical shaped member which is engaged by the outermost tubular member of the antenna assembly.

The spherical shaped member is mounted between the arms of a mounting means having first and second extruded openings which cooperate with the spherical shaped member to form a ball and socket joint about which the antenna assembly may be oriented to any desired angle and position. The spherical or ball shaped member slidably receives and engages the outermost tube of the telescoping antenna assembly permitting the antenna assembly to be moved to a collapsed position completely within the housing of the receiver unit.

The mounting clip means is a substantially -U-shaped member but is provided with first and second apertures in the topmost arm which are arranged to straddle the extruded opening of the arm for receipt of fastening members. The lower arm is provided with tapped apertures to straddle the extruded opening in the lower arm and are aligned to cooperate with the first and second apertures of the upper arm so as to receive and engage the fastening members which are inserted through the apertures of the upper arm.

A ball member which is a substantially cylindrical member having an outwardly extending flange at one end "ice thereof is designed to be received in the extruded opening of the lower arm with flange portion being seated in the extruded portion of the clip lower arm. The bottom portion of the ball member is seated upon the flange of a ferrule. The opposite end of the ferrule is designed to receive a substantially cylindrical insulating sleeve having a length which is equal to the length of the telescoping antenna in its collapsed position so as to fully insulate the collapsed antenna from live electrical elements within the receiver set housing.

The yoke portion of the U-shaped mounting clip has an are or curvature which is sufficient to permit spreading of the arms of the mounting clip for receipt of the antenna tube and rod assembly and the ferrule without distortion of the antenna clip during the insertion of the ferrule and antenna tube and rod assemblies to the extruded openings of the lower and upper arms respectively. The antenna is then ready for mounting to the housing of the receiver set. The antenna is secured to the receiver set housing by use of a fastening means which pass through the apertures in the upper arm and which threadedly engage the apertures in the clip lower arm. In addition to securing the antenna assembly to the receiver set housing, the lower arm of the clip, by adjustment of the fastening members, may beurged upwardly toward the clip upper arm in order to maintain suitable friction within the ball and socket joint so as to enable positioning of the antenna assembly in any desired angle with the assurance that the antenna assembly will retain its angular position due to the frictional forces. Due to the periods of continuous usage and wear, the frictional force diminishes and may become inadequate to retain the antenna assembly at any angular position. This may be readily and simply remedied by tightening the fastening members to readjust the adequate frictional engagement within the ball and socket joint.

In antenna mounting installations wherein it is desired to have the collapsed antenna assembly enter the receiver set housing at some angle from the vertical direction, this may simply be done by forming the extruded opening of the clip lower arm to a desired angle in order to permit the antenna tube and rod assembly to be guided v into the set at the desired angle.

The alternative embodiment of the instant invention is comprised of an alternative mounting clip having an opening for receiving the ferrule member and having first and second notches on opposite sides thereof forming a keyway for receiving the ferrule member which is provided with a pair of ears on opposite sides thereof for mating with the opening in the clip lower arm. The ferrule is provided with a flange at the upper end thereof for seating the ball shaped member in the same manner as previously described. The ferrule may be positioned with its flange resting upon the lower clip member byaligning the ferrule ears with the keyway opening. This arrangement provides sufiicient space for inserting the antenna tube and rod assembly without undue spreading of the clip arms. The antenna tube and rod assembly is mounted within a hollow dome-shaped member having an arcuate opening for receiving the tube and rod assembly therethrough. With the insertion of the tube and rod assembly together with the dome-shaped member in the clip upper arm opening, the ferrule member is lifted upward and twisted slightly so as to place the ferrule ears and lower clip opening notches out of alignment causing the lower clip opening to support the ferrule member at the lower end of the ferrule ears by bringing the arms of the clip member toward one another. This urges the flange portion of the ferrule clip into sliding engagement with the other side of the ball member so as to cooperate with the dome-shaped member and ball member to form the ball and socket joint.

The antenna assembly may then be mounted to the receiver set housing through the use of fastening members which pass through openings provided in the clip upper arm and which threadedly engage tapped openings in the lower clip anm. By suitable tightening of the fastening members the lower clip arm is urged upwardly toward the upper clip arm causing the ferrule flange to make firm engagement with the underside of the ball member providing the requisite frictional forces. The antenna tube and rod assembly may be collapsed and extended in the same manner as previously described. The dome-shaped member with its arcual opening permits the telescoping antenna to assume any angular position including a perfectly horizontal orientation which is not possible with the first embodiment described herein. Since the dome-shaped member is arranged to rotate within the clip upper arm opening, any azimuthal position may likewise be obtained by the antenna assembly.

The sliding engagement of the antenna tube and rod assembly outermost tubular member permits the tube and rod assembly to be totally collapsed and concealed within a receiver set housing, and the tube and rod assembly may be electrically insulated from the receiver set internal components by providing a vinyl insulating sleeve having a length substantially equivalent to the length of the tube and rod assembly in its collapsed form and by sliding the vinyl insulating sleeve over the lower end of the ferrule clip.

It is therefore one object of the instant invention to provide a novel telescoping antenna assembly for use in receiver sets and the like.

Another object of the instant invention is to provide a novel telescoping antenna assembly for use in receiver sets and the like and being arranged to be totally concealed with-in the receiver set housing.

Still another object of the instant invention is to provide a novel telescoping antenna assembly for use in receiver sets and the like comprising a mounting clip serving the dual functions of mounting the antenna tube and rod assembly through a receiver set housing and maintaining adequate pressure for the ball and socket arrangement.

Another object of the instant invention is to provide a novel telescoping antenna assembly for use in receiver sets and the like having a ferrule which is with a flange at one end thereof for seating the ferrule member of the antenna ball and socket joint.

Another object of the instant invention is to provide a novel telescoping antenna assembly for use in receiver sets and the like having a ferrule which is flanged at one end for seating the ball member of the antenna ball and socket joint, and further comprising a substantially U-shaped clip member and fastening means straddling the ball and socket joint for securing the antenna assembly to the receiver set housing and compressing the arms of the mounting clip for the purpose of increasing friction in the ball and socket joint.

Another object of the instant invention is to provide a novel telescoping antenna assembly for use in receiver sets and the like comprising a mounting clip having a notched keyway opening cooperating with a ferrule having cooperating cars which are insertable into the keyway to facilitate insertion of the antenna tube and rod to the mounting clip and further is positionable to support the ferrule upward against the ball and socket as sembly to maintain adequate frictional pressure therein, and further, comprising a hollow dome shaped member having an areual opening for receiving the tube and rod assembly therethrough to permit horizontal orientation of the tube and rod assembly when in its extended position.

These and other objects of the instant invention will eventually become apparent when reading the accompanying description and drawings in which:

FIGURE 6 shows a top view of the mounting clip in FIGURES 4 and 4a.

FIGURE 6a is a sectional view of the mounting clip of FIGURE 6 taken along the lines BB.

Referring now to the drawings, FIGURE 1 shows a telescoping antenna-assembly 10 designed in accordance with the principles of the instant invention and which is comprised of a rod element 11 and one or more cylindrical elements 12. These telescoping elements are so arranged that the rod 11 telescopes into the cylindrical tube of the next largest diameter and each succeed-ing cylindrical tube receives the adjacent tube of the next smallest diameter. The partially extended position of the telescoping elements is shown best in FIGURE 1 while the fully retracted position is shown best in FIG- URE 4.

The cylinder 12a of largest diameter houses all of the other cylinders 12 in the fully collapsed position, as well as rod 11 and is arranged to pass through and make sliding engagement with a ball member 13. Ball member 13 is provided with a suitable opening which creates frictional engagement between ball member 13 and tube 12a. When tube 12a is positioned in any desired attitude, this position will be retained without danger of tube 12a slipping due to gravity. This frictional engagement also exists between neighboring telescoping elements of assembly 12a, 12 and 11, simply by providing a suitable degree of pressure between these elements. It should also be understood that the elements are adequately interlocked so as to prevent a removal of any of the telescoping elements from any of its neighboring elements under normal use.

The ball member 13 forms a ball joint (or ball and socket joint) with the extruded portions of mounting clip 14 which is also shown in FIGURES 2, 2a and 3. The mounting clip 13 is a substantially U-shaped clip which may be formed from a flat sheet of relatively resilient metallic material and is provided with a yoke or central portion 15 having upper and lower arms 16 and 17 respectively extending in essentially the same direction from yoke portion 15. The central or yoke portion is cut in such a manner as to form the outward ear 18 having an aperture 19 for making electrical connection between the antenna assembly and a conductor (not shown) extending to the receiver electronics portion.

Upper arm 16 of clip 14 is provided with an opening 20 which is extruded so as to form the continuous flange 21. Two apertures 22 and 23 are provided in upper arm 16 which apertures are positioned astride the extruded opening 20 for a purpose to be more fully described and which are designed to receive suitable fastening members.

The lower arm 17 is provided with an opening 24 which is extruded so as to form the continuous flange 25 surrounding the opening. The lower arm 17 has its free end bent at the locations 26 and 27 so as to place the free end 28 in close proximity to the free end of upper arm 16. Two tapped apertures 29 and 30 are provided in lower arm 17 which are astride the extruded opening 24 and are designed to threadedly engage suitable fastening means to mount the clip means to the receiver set housing in a manner to be more fully described.

The extruded opening 24 in lower arm 17 is designed to seat a ferrule member '31 which is a substantially cylindrical shaped member which is bent along its upper marginal edge to form a continuous outwardly facing flange 32. The diameter of the flange 32 of ferrule 31 is substantially greater that the diameter of the extrudcd opening 24 to as to permit the lower arm extruded opening 24 to seat ferrule 31 in a manner shown in FIGURE 1.

The ball and socket assembly is comprised of a ball member 13 which makes sliding engagement with the flange 32 of ferrule 31 as well as the fiange 21 of extruded opening 20 in upper arm 16.

The manner in which the elements of the telescoping antenna assembly of FIGURE 1 are assembled can best be understood upon a consideration in FIGURE 3. The mounting clip 14 is suitably punched and formed so that its arms are positioned relative to one another in the manner shown in FIGURE 3. The radius of curvature of the yoke portion 15 of mounting clip 14 is sufficient however to permit the arms 16 and 17 to be spread apart a greater distance than that shown in FIGURE 3 without experiencing any distortion of the mounting clip. With the arms spread as shown, the ferrule 31 may be inserted into extruded opening 24 in the manner shown by arrow 33.

The telescoping tube and rod assembly comprised of rod 11, tubes 12 and ball member 13 is then inserted through the extruded opening in the direction shown by arrow 34. After insertion of the elements the assembly 10 is positioned with the upper arm 16 of clip 14 being placed against the underside of the mounting surface 35 which may, for example, be the housing of the receiver set (not shown). The mounting surface 35 is provided with an aperture suitable for receiving the telescoping elements 11 and 12 as well as ball members 13 therethrough. Additional apertures 37 and 38 are provided in mounting surface 35 for receiving the threaded fastening members 39 and 40. The threaded portions of fastening members 39 and 40 pass freely through the apertures 37 and 38 in mounting surface 35, and the apertures 22 and 23 in upper arm 16 while making threaded engagement with the tapped apertures 22 and 23 provided in lower arm 17.

By tightening the fastening screws 39 and 40 with a screwdriver, for example, the threaded engagement between screws 39 and 40 and apertures 22 and 23 respectively causes the lower arm 17 to be urged upwardly in the direction shown by arrows 41 thereby urging the flange 32 of ferrule 31 into firm engagement with the underside of ball member 13.

In the fully collapsed position the antenna assembly telescoping elements 11 and 12 extend through the center of ferrule 31. When the telescoping elements are lifted vertically upward, they are removed from ferrule 31 thereby permitting the tube and rod elements to be oriented at substantially any angle desired from the vertical, for example, the tube and rod elements may be oriented to the dotted line position 42 shown in FIGURE 1. The tube and rod elements once moved to this position will retain this position due to the firm frictional engagement between the ball member 13 and the flanges 21 and 32 provided in clip upper arm 16 and ferrule 31 respectively.

If a portion or all of the frictional engagement provided in the ball and socket joint is lost due to continued use of antenna assembly 10, this may be simply and readily corrected by further adjustment of the fastening screws 39 and 40. Either one or both of these screws may be further adjusted so as to move clip lower arm 17 to restore firm engagement beween ferrule flange 32 and ball member 13. Even through the free end portions of the mounting clip arms 16 and 17 may be in engagement with one another as shown in FIGURE 2a, the resiliency qualities of the mounting clip 14 coupled with the curvature of yoke 15 are selected to permit further upward movement of lower arm 17 in order to restore the desired frictional pressure for the ball and socket joint.

In order to protect the tube and rod elements 12 and 11 against making electrical contact with components and/or live elements in the receiver set housing, a vinyl insulating sleeve 43 is provided having one end thereof positioned around the lower end of ferrule 31. The insulating sleeve 43 has a length sufficient to fully enclose the antenna assembly in its collapsed position so as to electrically insulate the antenna from any elements within the receiver set housing.

In applications where the design of the receiver set is such as to require the tube and rod elements 12 and 11 respectively to be guided into the receiver set housing at some angle from the vertical, the extruded portion 25 of opening 24 may be formed in the manner 25' shown in the insert 44 of FIGURE 2 so as to position the ferrule 31 shown in dot-ted fashion at an angle to the vertical center line 45 which thereby permits the tube and rod elements 12 and 11 respectively, to be guided into the receiver set housing at substantially the same angle.

FIGURES 4 and 4a show an alternative embodiment of the instant invent-ion which is comprised of tube and rod elements 12 and 11 respectively, substantially identical to the elements shown in FIGURE 1 with these elements being shown in the collapsed position. The outermost tubular element 12a can be seen to project through the ferrule member 31'.

The assembly 50 further comprises a dome-shaped ele ment 51 which is also shown in detail in FIGURES 5a and 5b and has asubstantially cylindrical shaped base portion provided with a continuous flange 52 at the lower end thereof. The cylindrical base portion forms the dome-shaped portion 52 at the upper end thereof which is provided with an arcual shaped opening 53 for receiving the tube and rod assembly therethrough with the dome portion 52 of member 51 receiving the ball member 13. The mounting clip 14 of assembly 50 is also shown in FIGURES 6 and 6a and is provided with a yoke portion 15, car 18 and upper and lower arms 16 and 17 which are substantially identical to the mounting clip of FIG- URES 2 and 2a. The apertures 22 and 23- and the tapped apertures 29 and 30 in the embodiment of FIGURES 4, 6 and 6a are also substantially identical to those likenumbered apertures shown in FIGURES 2 and 2a. Upper arm 16 of embodiment 14 is provided with aperture 52 which differs from the aperture 20 of FIGURES 2 and 2a in that it is not extruded.

The lower arm 17 is provided with an aperture 53 which differs from the aperture 24 in that it is not extruded and further in that it is provided with two notches 54 and 55 substantially on opposite sides thereof.

The opening 53 and notches 54 and 55 form a keyway for receiving the ferrule 31' which is provided with a flange 32 at itsupper end and which further is provided with cars 56 and 57 which are received by the cooperating notches 54 and 55 respectively in a manner to be more fully described.

The assembly of the embodiment 50 can best be understood from a consideration of FIGURE 4a. The mounting clip after being formed and stamped has its arms 16 and 17 in the position shown in FIGURE 4a. The ferrule 31' was inserted into the opening 53 in the direction shown by arrow 58. After insertion of the lower end of ferrule 31' into opening 53, the ferrule is then rotated until the ears 56 and 57 are in alignment with the notches 54 and 55 respectively.

After insertion of ferrule 31' in the above manner, the tube and rod. assembly 12 and 11 together with the ball member 13 and dome-shaped member 51 are inserted into the opening 52 in the direction shown by arrow 59 so that the flange 52 rests against the underside of clip upper arm 16. After insertion of the antenna elements, the ferrule 31' is lifted upwardly in the direction shown by the arrow 60 so as to completely remove the ears 56 and 57 from the cooperating notches 54 and 55 respectively. As soon as the ears 56 and 57 are free from their associated notches, the ferrule 31 is then rotated preferably by a Mt turn or 90' to the position shown in FIGURE 4 so that the lower ends of cars 56 and 57 rest upon the upper surface of arm 17. With the ferrule 31' in the position shown in FIGURE 4, it can clearly be seen that the upper flanged end of ferrule 31 extends well into the interior of domeshape member 51 so as to seat the ball member 13 on its flange 32. The advantage of using the dome shaped member 51 in the assembly 50 lies in the fact that the antenna tube and rod assembly may be oriented to any angular position including a completely horizontal orientation which are shown by the sections of the tube and rod assembly 12' of FIGURE 4a. Ears 56 and 57 on ferrule member 31' provide for the adequate positioning of ferrule flange 32 so as to provide firm engagement between the flange 32 and the ball member 13 to provide the requisite frictional engagement therebetween. The keyway arrangement comprised of the notches 54 and 55 in mounting clip 14 permits the ferrule 31' to be positioned as shown in FIGURE 4a to enable insertion of the tube and rod assembly as well as the ball and dome-shape members 13 and 51 respectively without bending mounting clip 14' so that it becomes permanently distorted. Thus, the ferrule 31 being provided with ears 56 and 57 cooperate with the opening 53 having notches 54 and 55 to permit relatively simple assembly of the elements without distortion of the mounting clip, at the same time providing the requisite frictional engagement for the ball and socket joint.

The arcuate shaped opening 53 in dome shaped member 51 permits the antenna assembly, when fully extended, to move between horizontal and vertical limits. The dome-shaped member 51 is slidably engaged by the marginal edge of opening 52 in mounting clip upper arm 16 so that it may experience rotation about its longitudinal axis to permit azimuthal orientation of the extended antenna assembly to any possible position desired.

By insertion of the fastening screws 39 and 40, in the same manner as previously described with respect to FIG- URE 1, the antenna assembly 50 may be mounted to the mounting surface 35 with fastening screws 39 and 40 acting to adjust the position of mounting clip arm 17 relative to upper arm 16 in order to provide adequate frictional engagement between ball 13 and flange 32 of ferrule 31. Adjustment of screws 39 and 40 act to urge lower arm 17 upwardly against the lower edges of cars 56 and 57 to provide the requisite frictional engagement of the ball and socket joint.

In cases where it is desired to disassemble the antenna assembly, this may be readily done by reversing the steps of assembly merely by rotating ferrule 31' by a A turn to cause ears 56 and 57 to re-enter the cooperating notches 54 and 55 respectively, thereby facilitating in the removal of the upper assembly comprised of dome 51, ball 13 and tube and rod members 12 and 11 respectively. The ferrule 31 may then be removed from the mounting clip 14 without distorting the knee or yoke portion of the clip.

In cases where it may be desirable to provide an antenna dipole arrangement for receiver units and the like, this may be provided for very simply by employing two assemblies of either type or 50 shown in FIGURES l and 4 respectively, and mounting them adjacent one another on the same receiver set housing. The assembly 50 of FIGURES 4 and 40 may also be provided with a vinyl insulating sleeve 61 which is positioned about the lower end of ferrule 31 and which has a length substantially sufficient to envelope the tube and rod assembly when in its fully collapsed position in order to electrically insulate the assembly from any internal live elements. In order to provide firm engagement between ferrule 31 and sleeve 61 the ferrule is provided with a flared lower end 62 over which the sleeve 61 is positioned. A resilient metallic mounting clip 62 further acts to prevent movement of the sleeve 61 once it has been positioned around ferrule 31'.

The adjustable features described with respect to the embodiment of FIGURE 1 are also present in the embodiments of FIGURES 4 and 4a and it should be understood therefore that frictional pressure can be restored by a simple adjustment by the receiver set owner at any time. As to the installation thereof, this may be effected by use of a screwdriver (not shown) and thereby requires no special training or special purpose tool to provide or restore the requisite frictional engagement needed to assure the fact that the antenna assembly, once in the extended position will retain that position indefinitely until moved by the operator to some other position.

It can therefore be seen that the instant invention provides a novel mounting assembly for telescoping antennas which is simple in design, may be simply and readily assembled and disassembled, and which provides for simple readjustment throughout its operating life in order to restore the requisite frictional engagement of its ball and socket joint, and which utilizes the same screws employed for mounting for the purpose of making the ball and socket joint adjustment.

Although there has been described a preferred embodiment of this novel invention, many variations and modifications will now be apparent to those skilled in the art. Therefore, this invention is to be limited, not by the specific disclosure herein, but only by the appending claims.
